Hydroxyethyl Cellulose
Cosmate HEC,is a cellulose etherified with hydroxyethyl groups to give the desired properties,is a nonionic water-soluble polymer,is a white,free-flowing granular powder.It’s insoluble in organic solvents,but it is ealisy dispersed in cold and hot water to give solution of varying viscosities.
Cosmate HEC is used as a thickener,protective colloid,binder,stabilizer,and suspending agent.In personal care sector,Cosmate HEC is used in thickening shampoos,conditioners,liquid soaps,masks,and shaving creams.
